Defendant requests your Honor to charge the jury that the burden in this case rests with the commonwealth, from the beginning to the end of the trial, to establish, beyond a reasonable doubt, every fact essential to the conviction of the defendant, and if the commonwealth has failed to prove such charge beyond a reasonable doubt, the defendant is entitled to an acquittal.
VIII
Defendant requests your Honor to charge the jury that the unintentional killing of a human being by another without motive, intent, premeditation, is neither murder nor manslaughter.
IX
Defendant requests your Honor to charge the jury that the questions of deliberation and premeditation, intent and motive, are purely questions of fact, to be determined by the jury from the evidence alone.
X
Defendant requests your Honor to charge that if the jury cannot say, beyond a reasonable doubt, that the defendant was sane at the time of the commission of the act, and cannot say whether, at that time, he was sane or insane, the defendant must be acquitted.
XI
Defendant requests your Honor to charge the jury that if, at the time the defendant committed the act charged against him, upon seeing the deceased, he was thrown into a state of mind from which he was deprived of his understanding, so as to be unaware of the nature and quality of the act he committed, or so as to be unable to distinguish between right and wrong in reference to that particular act at the time of its commission, this defendant must be acquitted.
